Struct packet_formats::utils::NonZeroDuration

pub struct NonZeroDuration(/* private fields */);

A thin wrapper over a Duration that guarantees that the underlying Duration is non-zero.

Implementations

impl NonZeroDuration

pub const unsafe fn new_unchecked(d: Duration) -> NonZeroDuration

Creates a non-zero without checking the value.

Safety

If d is zero, unsafe code which relies on the invariant that NonZeroDuration values are always zero may cause undefined behavior.

pub const fn from_secs(secs: u64) -> Option<NonZeroDuration>

Creates a new NonZeroDuration from the specified number of whole seconds if that number is non-zero.

pub const fn from_nonzero_secs(secs: NonZeroU64) -> NonZeroDuration

Creates a new NonZeroDuration from the specified non-zero number of whole seconds.

pub const fn from_secs_nanos(secs: u64, nanos: u32) -> Option<NonZeroDuration>

Creates a new NonZeroDuration from the specified number of whole seconds and additional nanoseconds if the resulting duration is non-zero.

If the number of nanoseconds is greater than 1 billion (the number of nanoseconds in a second), then it will carry over into the seconds provided.

Panics

This constructor will panic if the carry from the nanoseconds overflows the seconds counter.

pub const fn from_nonzero_secs_nanos( secs: NonZeroU64, nanos: NonZeroU32 ) -> NonZeroDuration

Creates a new NonZeroDuration from the specified non-zero number of whole seconds and additional nanoseconds.

If the number of nanoseconds is greater than 1 billion (the number of nanoseconds in a second), then it will carry over into the seconds provided.

Panics

This constructor will panic if the carry from the nanoseconds overflows the seconds counter.

pub const fn from_millis(millis: u64) -> Option<NonZeroDuration>

Creates a new NonZeroDuration from the specified number of milliseconds if that number is non-zero.

pub const fn from_nonzero_millis(millis: NonZeroU64) -> NonZeroDuration

Creates a new NonZeroDuration from the specified non-zero number of milliseconds.

pub const fn from_micros(micros: u64) -> Option<NonZeroDuration>

Creates a new NonZeroDuration from the specified number of microseconds if that number is non-zero.

pub const fn from_nonzero_micros(micros: NonZeroU64) -> NonZeroDuration

Creates a new NonZeroDuration from the specified non-zero number of microseconds.

pub const fn from_nanos(nanos: u64) -> Option<NonZeroDuration>

Creates a new NonZeroDuration from the specified number of nanoseconds if that number is non-zero.

pub const fn from_nonzero_nanos(nanos: NonZeroU64) -> NonZeroDuration

Creates a new NonZeroDuration from the specified non-zero number of nanoseconds.

pub const fn new(d: Duration) -> Option<NonZeroDuration>

Creates a non-zero if the given value is not zero.

pub const fn get(self) -> Duration

Returns the value as a Duration.

impl Ord for NonZeroDuration

fn cmp(&self, other: &NonZeroDuration) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
